How well does the copper platting on Rainier bullets hold up? I was thinking about using some of there 300g .500cal plated HP bullets for reloading .50AE. Can they handle the 1400fps and 35,000psi sammi chamber pressures? I have heard of Berrys bullets platting stripping off over 1200fps. I really don't want to clog up my gas port as it is inaccessible for cleaning.The rifling is octagonal like a glock.
